To celebrate November sweeps, Fringe’s very charming and very talented John Noble (Walter Bishop) gave a conference call interview, during which he discussed Walter’s relationship with his son, Peter (Joshua Jackson), where he draws inspiration for his character, and just how much fun he has playing the mad scientist.

The question on how much fun he has playing the character opened the interview. Noble laughed and answered, “It’s as much fun as it looks like. I mean it’s an absolute hoot playing. It’s obviously got serious aspects to it, but I treat it as a hoot to play the thing. Preparation, well, that’s probably the hardest bit, getting the timing right and doing the preparation on the scientific work. But working on Fringe is a great job.”

Despite being on Fringe, Noble admitted that he has to work to keep up with the twists and turns of the plots. He doesn’t see that as a drawback, though, and said, "As an audience member, I kind of enjoy reading things that make me concentrate or watching things that make me concentrate ... I watched an episode on Tuesday night, and I was in it, but there were things I missed, and I said, 'What was that? What did they say there?' It’s fascinating to be watching something that does require concentration."

The actor said that he has always had a good head for theoretical, if not practical, science, and that he based a lot of Walter on a good friend of his from university with whom he used to talk science. He noted, "Whatever he did, it was with complete and utter focus. That’s one of the aspects that Walter has as well."

This brought up the question about just how focused Walter can be, at the expense of his family life, and Noble agreed that "Walter is incredibly focused, myopic when he has a task to do, and really other things become secondary." Given that his son, Peter, was sometimes one of those "other things," the Fringe star said both he and co-star Joshua Jackson found the father/son relationship "was something that touched us both and interested us both, and so we became very animated right from the beginning, Josh Jackson and I, about the responsibility of playing this correctly, getting this right. And we still talk about it. We still get excited about it."
